javafx - Convert an IntegerBinding to a DoubleBinding -


this may seem simple question, turns out it's not easy (or can't find info on how this).

i want convert integerbinding have, namely bindings.size(families); doublebinding if bindings.divide(bindings.size(families),bindings.size(familiesall)) don't result of integerdivision. maybe there otherways achieve want, converting bindings essential must possible.

a couple of options:

bindings.createdoublebinding(() ->      1.0 * families.size() / familiesall.size,      bindings.size(families), bindings.size(familiesall));

or:

bindings.divide(bindings.size(families).add(0.0), bindings.size(familiesall));

or:

bindings.size(families).add(0.0).divide(bindings.size(familiesall));

or:

doubleproperty familiessize = new simpledoubleproperty(); familiessize.bind(bindings.size(families)); bindings.divide(familiessize, bindings.size(familiesall));

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
